Measurement

Jessica • 2 miscarriages and a chemical within the last year, now expecting a 🌈 baby.

At my 8 week scan I was told my due date was 1-21 which would now put me at 11w...but today I went in and now my due date is 1/25 and I am measuring 10w4d. Is that normal? Heart rate at the first was 171 and now it’s 172 . I am worried I am measuring off now.
